GitHub - oh-my-fish/plugin-foreign-env: Run foreign bash scripts and capture exported environment variables (original) (raw)
Foreign Environment
A foreign environment interface for Fish shell
Foreign environment wraps application execution in a way that environment variables that are exported or modified get imported back into fish. This makes possible running popular bash scripts, like the excellent nvm.
Install
Be sure to have Oh My Fish installed, so you just need to:
If you dislike shell frameworks, you can still use Foreign Environment in Fish! Clone this repo somewhere and append to your ~/.config/fish/config.fish:
set fish_function_path $fish_function_path /functions
Usage examples
You can use bash syntax to export variables:
fenv export PYTHON=python2
This will have the same effect as typing:
You can also call multiple commands, separated by semicolon:
fenv source ~/.nvm/nvm.sh ; nvm --help
When commands aren't double quoted, you need to escape semicolon with slash \; to prevent fish from interpreting it. Or just quote the whole command:
fenv "source ~/.nvm/nvm.sh; nvm --help"
Caveats
- Currently we only handle environment variables that are added or modified. If a variable is unset (removed from environment) it will not be removed from fish.
